4. Install the oil drain plug with a new gasket.

Tightening torque :
34.3 - 44.1N.m (3.5 - 4.5kgf.m, 25.3 - 32.5lb-ft)

5. Fill with new engine oil, after removing the engine oil level gauge.

6. Install the oil filler cap.
7. Start engine and check for oil leaks and check the oil gauge or light for an indication of oil pressure.
8. Recheck the engine oil level.

Inspection

1. Check the engine oil quality.
Check the oil deterioration, entry of water, discoloring of thinning. If the quality is visibly poor, replace the oil.
2. Check the engine oil level.
After engine warm up stop the engine wait 5 minutes then check the oil level. Oil level should be between the "L" and "F" marks on the dipstick. If low check for leakage and add oil up to the "F" mark.

NOTE:
Do not fill with engine oil above the "F" mark.

Selection Of Engine Oil
Recommendation : 5W-20/GF4&SM (If not available, refer to the recommended API or ILSAC classification
API classification: SL, SM or above
ILSAC classification : GF3, GF4 or above
SAE viscosity grade : Refer to the recommended SAE viscosity number

Factory service manual diagram




NOTE:
For best performance and maximum protection of all types of operation, select only those lubricants which :
1. Satisfy the requirement of the API or ILSAC classification.
2. Have proper SAE grade number for expected ambient temperature range.
3. Lubricants that do not have both an SAE grade number and API or ILSAC service classification on the container should not be used.
